Apple is continuing to fine tune the upcoming watchOS update for Apple Watch ahead of the software update’s release this fall, and now registered developers can test their apps against the latest build as watch OS 2 beta 5 is now available.

The watchOS 2 update allows developers to build native (read faster) apps that do not rely as much on the iPhone for processing power, third-party complications or widgets for the watch face, and closer access to hardware like heart rate sensor data and more. For consumers, watchOS 2 adds new features like Nightstand Mode, using photos or albums as a watch face, and various app refinements.

The last watchOS 2 beta notably added support for colored complications including Activity with increased legibility on certain watch faces including Utility and Modular. We’ll explore the latest watchOS 2 beta to find other new changes coming this fall, and let us know if you discover any differences between the last beta as well.
